Preparation of Micron Silver Powder by Multistep Reduction and its Crystal Growth Characteristics AITranslate
Abstract AITranslate
Micron silver powder was prepared by step-by-step reduction in aqueous solution with ascorbic acid as the reducer and PVP as the dispersant. The growth pattern of silver particles at different reactant dropping rate and silver nitrate dosage was investigated by SEM and XRD, and their growth mechanism was studied by AFM. The results show that when the reactant dropping rate is 1 mL/min,uniform mono- disperse silver particles with an average diameter of 1. 8 /~m can be obtained, and particle size increases nearly linearly with the dosage of silver nitrate. The silver crystal grows through layered growth mode and step-cluster approach,which belongs to Kossel-Stranski two-dimensional nucleation model.
